Remarks
This IOCTL sends the WODM_BT_SCO_AUDIO_CONTROL message to the audio driver to disable audio routing. Other AG service IOCTLs do not communicate with the audio driver.
To open an audio connection to the headset or the hands-free device, use the IOCTL_AG_OPEN_AUDIO IOCTL.
To route audio to the headset or to the hands-free device independent of the Network Component, you must first open or close an audio connection.
